The Magpies' new director of football has been slammed by the Geordie icon following a gaffe-ridden radio interview and the resignation of managing director Derek Llambias.
The former Wimbledon boss was officially announced in his new role on Tuesday, with the club revealing that both manager Alan Pardew and chief scout Graham Carr would report directly to Kinnear.
Shearer has lambasted the appointment of Kinnear, and believes the 66-year-old – who conducted a gaffe-ridden radio interview earlier this week – has turned Newcastle into a laughing stock.
“Right now people are laughing at the football club I support,” wrote Shearer in The Sun. “And that sickens me. I promised myself years ago never to be surprised by what happens in football — particularly when it comes to Newcastle. But this situation really is stretching it a bit.
"While other clubs are all plotting and planning for next season, Newcastle have a manager who has just been totally undermined. Alan Pardew has said he will carry on but I am sure it will be a difficult situation. I ask one question of Joe Kinnear: Would you stand for it, if you were manager? As for that announcement, what are the players to think when he can’t even get their names right. It’s all a PR disaster.”
